Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738556, here are decompositions:

17 + 8738539 = 8738556
23 + 8738533 = 8738556
83 + 8738473 = 8738556
107 + 8738449 = 8738556
109 + 8738447 = 8738556
149 + 8738407 = 8738556
157 + 8738399 = 8738556
173 + 8738383 = 8738556

Showing the first eight; more decompositions exist.
